Inside "make menuconfig" it's selected:
x86-Generic-Generic
Taget images-VirtualBox VDI
additional Kernel modules-Filesystems-kmod-fs-isofs
no other packages or modules selected outside the given defaults.

I'm also wondering why kmod-fs-ext4 and kmod-fs-vfat are build but not shown inside "Kernel modules-Filesystems" as selected.
Neither <M> or <*> nor as depended -*-.
Is this inconsistency wanted ?
